You can always say, no you didn't v but you felt very ill. Not everyone v's with a sv. I usually don't.

Don't feel like a baby. You didn't feel well so you went home...people do this all the time.

You won't necessarily get it. Just clean, clean, clean and wash your hands. Can you use a different bathroom than your husband? My hubby had it last year and I asked him to stay in our room and use our bathroom. He did and no one else got it. I just slept in another room and used a different bathroom. When he was better, I went in with gloves and cleaned with bleach.
